The 3-1/2 Inch Palm Nailer (NH90AB) accepts a 2-1/2 - 3-1/2 inch bulk fastener while offering superior maneuverability when working in confined areas. It is ideal for installing joist hangers and metal connectors. Its 360-degree swivel plug allows the hose to hang at any angle instead of straight out adding convenience when working in tight spaces. The over-molded rubber grip provides comfort, absorbs vibration, and improves control.
